WILLIAM J. JOHNSON, OF NEWTON, ASSIGNOR TO HIMSELF AND HENRY A.HILDRETH, OF LOVELL, MASSACHUSETTS.

IMPROVEMENT IN CORN-POPPERS.

Specification forming part of Letters Patent NO. 116,600, dated July 4,1871.

To all whom vit 'may concern:

Be it known that I, WILLIAM J. JOHNSON, of Newton, in the State ofMassachusetts, have in- Vented certain new and useful Improvements inCorn-Poppers, of which the following, with the drawing, is a fulldescription:

My improvements consist in a new method of constructing the binding andof attaching the screw-shank to the binding and the wire brace of thepopper, as well as the construction of the screw-Shank for the purpose.

In the drawing, Figure lis an upper-side View of the screw-shank. Fig. 2is a top view of the shank attached to the body of the popper. Fig. 3 isa section ofthe shank and wire brace. Fig. 4 is an under-side View Of acorner Of my improved binding. Fig. is a similar View of the old kind ofbinding. Fig. 6 is a side View ofthe Ol d binding as prepared to ben dand form a con ner. Figs. 7 and are sections of the binding attached tothe wire Of the popper-body.

In the drawing, A represents the screw-sha1 ik; B, the wire brace; O,the wire cloth Of the body of the popper. D is the bindin of sheet metalbent over the top edges of the wire-cloth body, which is formed intoshape by dies or otherwise. a. a are fork-like proj eetions ony thefront end ofthe screw-shank. b is a brace or bar across the bottom andnear the middle ofthe Open cavity, between the tines of the fork; and ois a brace or bar across the top and near the front Of this cavity. d isthe rear end of the wire brace, which enters the cavity Of thescrew-shank. e is the corner of the binding, Of which `f is the insideand h the Outside iiap.

In the Old-style poppers the inside flap f of the binding has atriangular piece, e, Fig. 6, cut out before the binding is bent to forma corner. When bent it appears as in Fig. 5. My improvement consists incorrugatin g the inside flap when the corner is bent without cutting it,as appears in Fig. 4. By this means the binding-edge Of the popper isgreatly strengthened and stiifened at the corners. The binding is put onthe wire body and fastened to it in the usual way. My screwshank isconstructed with an Open cavity Or recess at its front, having a braceor bar, c, across its top, near the front ofthe tines a a, and anotherbrace or bar, b, across its bottom, near the middle, forming a liind'oflnortise, into which the rear end d Of the wire brace B enters under oand over b. The front Of the screw-shank, which is of malleable metal,has two' fork-like proiections, a a, which pass through holes in thebinding, and are clinched down, a-s in Fig. 2. In this manner the shankis iirmly attached to the body of the popper, and it also firmly holdsthe end d of the wire brace, which is slipped into the cavity of theshank. The brace is Otherwise attachcd to the body of the popper infront, in the usual manner.

l. The screwshank, with malleable ti nes a and brace b, substz'l-ntiallyas described.

2. The binding, crimped or corrugated at its corners, substantially z sset forth.

3. The combination of binding, wire brace, and screw-shank, sever-allconstructed and arranged in relation to each other substantially asshown.

4. The corn-popper, with body, binding, wire brace, and screw-shankcombined, when severally constructed and arranged substantially asdescribed.

In testimony whereof I have hereunto subscribed my name.
